The most likely statement to explain the change in the proportion of green toads increasing from 20% to 50% over 50 years is:

"The environment changed such that green toads can blend into their surroundings better."

This statement suggests that the increase in green toads is likely due to a selective advantage conferred by their coloration in a changing environment, allowing them to avoid predation and reproduce more successfully.
